Application filed August 9, ieaajserial ITO/212,706.

This invention relates to gripping tools a of the pliers type, and whileparticularly de-' signed and adapted as a jar cap remover, it isunderstood that the same may be employed in other capacities in whichit'maybe used.

, jaws are'associated with caps of large diameters, is practicallyimpossible.

It is therefore an object of the present inventionto provide a grippingtool in which at least one jaw and its operating handle are relatively.adjustable to compensate for the use ofthe tool upon objects of varyingdiameters. I i

The invention furthermore comprehends in a gripping tool of; thecharacter set forth, a simple and effective adjustable connectionbetween atjaw and its operating handle;

With the above recited and other objects inview, reference is had to thefollowing description and accompanying drawings in which there isexhibited one example or embodiment of the invention, while i theappended claims define the ac'tual scope of the invention. I In thedrawings- I Figurell'is a plan view ofthe tool with the jaws in closedcondition and illustrating the adjustable operating handle adjusted forminimum sized objects to be gripped;

Fig. 2'is a similar vlew with the jaws opened and illustratingtheadjustable handle adjusted to the position for gripping objects of amaximum size; a

I Fig. 3 is a fragmentary plan view illustrating the adjustable handlein an; intermediate disengaged position with respect to its jaw;

Fig. 4: is an enlarged fragmentary sectional' view taken approximatelyon the line 4-4 of Fig.2. I Referring to the drawings by characters ofreference, 10 and 11 designate a pair of gripping jaws, which may be ofany desired configuration, which in the present instance are of arcuateshape and providedon the inner concave faces with gripping teeth 12 sothat the tool may be employed for gripping and turning circular articlessuch as ar caps. substantially circular base or hub 13, WhlCh The jaw 10is provided with a base has extending from a substantially diametricallyopposite point from which the jaw extends, a -handle-shank 14 carrying ahandle "The handlev'shank 14: may be either integral or otherwiserigidly connected with the jaw base 13. The other I jaw 11 is providedwith "a similar circular base orhub =16 which overlies the baseor hub 13and through which bases or hubsa pivot 17 axially extends to pivotallyconnect the jaws for relative opening and closing movement. An operatinghandle '18 for the j awnlli in-, cludes a shank 19, which is provided"with'a slotted end 20 through which-the pivot bolt 17 also extends. 16of the jaw ll-atga pointsubstantially spaced notches or recesses 21,while the hanadapted for selective engagementin therehandle 18atrelatively different angularly the handle longitudinally'to normallyen- The peripheral base'or hub diametrically opposite the jaw '11, ispro- "vided with a plur'alityofcircumferentially i 'cesses'or'notches21'to dispose the'operating so adjusted positions with'respect to the jaw 11. In order to pro'videmeans for sliding gage and"retainthe detent 22 within the j notches or recesses 21,-

coiled expansion spring'23 is positioned within the slot 20,

the opposite ends" bearing respectively against the pivot b0lt'1-7Hand.the outermost end of the slot 20 In order-to prevent derangement orpositive accidental. displace ment'of the springfrom the; slot, theouter .end cconvoluti'on vof the v spring is provided' with an axialoutwardly projecting terminal 24 which extends into an opening 25 in theextremity of the handle shank 19. In

order to limit outward sliding movement ofy the handle to a point wherethe detent clears the periphery of the base or hub 16 of the i awvolutions of the spring 23 so that its opposite ends are engagedrespectively bythe, outermost end of the slot and the pivot bolt In use,when a jar cap or objectof a minimum size is to be gripped and turned bythe tool, the detent 22 is engaged in the recess or notch 21 which willdispose the handle in 11, a pin 26 is arranged within the con- I such a,position'that whens-the tool jawsare I I may be. engaged in one of theremaining notches suitable to the particular diameter of the object tobe gripped. This disposes the jaws l and 1-1 in an open position whenthe handles are in substantially parallel1relation so that an undulywide separation of the handles to obtain a, grip ontheobjecg isunnecessary. It therefore follows that the operator may employ one handfor setting up the desired grip of the jaws upon the ole: jectito begripped and turned. Inadjusting the handle 18, itis only necessary topull out-j ward'lyagainst the action of the spring 23 until the detent22is completely disengaged fromthe notch or recess 21 with which it isengaged and then to turn the handle relas tive to the base 01' hub 16 ofthe-jaw 1 1, 11

'- It (is, ofcourse, to i be understood, within the scopeoi theinvention, that bothjaws niayhagve their handles adjustably connected'therewith ifrsodesired so as to further in-v crease the variationor"theadjustment ofthe tool. A
